Basic SEO Question:
“How much time is Google taking to index a new webpage, and how can we accelerate the process besides using Google Webmaster Tools?”
The simple answer is to get more links. Pages can be indexed in seconds or minutes IF you’re linked on other credible sites.
By having lots of links on other sites, you’ll be looked at as “useful” by search engines like Google and their search engine spiders will come back often to “re-index” your content, including new pages or blog posts you’ve created.
One recommendation I give clients to monitor how soon new pages get indexed is to set up a Google Alerts process.
